Scatter Gather DMA Engine - Validates efficient scatter-gather DMA for high-performance data transfer

Overview

Key Features

• Flexible Descriptor Management: Supports dynamic descriptor chains for handling non-contiguous memory regions. Ensures efficient data transfers across varying buffer configurations, improving overall memory management.
• High Throughput Validation: Simulates high-speed data transfers with minimal CPU intervention. Verifies that DMA operations are efficient and capable of handling large volumes of data.
• Protocol Compliance Checking: Validates adherence to standard DMA protocols, ensuring correct signaling and timing. This prevents communication errors between DMA controllers and memory systems.
• Error Injection Capabilities: Allows for fault tolerance testing by injecting errors such as checksum issues or misaligned memory accesses. Verifies the robustness of the DMA controller’s error recovery mechanisms.
• Multi-Channel Support: Verifies the simultaneous operation of multiple DMA channels. Ensures proper arbitration, channel prioritization, and resource allocation for multi-threaded applications.
